Quality adjustment using a fragmented media stream

An apparatus, comprising:

• an input interface configured to receive a first request from a user for playback of a media program on a first device supporting a first quality level and a second request from the user for playback of the media program on a second device supporting a second quality level different from the first quality level;
• a memory configured to maintain a media program position for resuming playback for the user;
• an output interface configured to transmit a first fragment associated with the media program encoded at the first quality level to the first device, the first fragment including a first fragment number and a box structure supporting synchronization information and end of file information;
• wherein a second fragment associated with the live media program is transmitted to the second device, the second fragment including a second fragment number derived using the media program position.

A computer readable storage medium, comprising:

• computer code for receiving a first request from a user for playback of a media program on a first device supporting a first quality level;
• computer code for transmitting a first fragment associated with the media program encoded at the first quality level to the first device, the first fragment including a first fragment number and a box structure supporting synchronization information and end of file information;
• computer code for receiving a second request from the user for playback of the media program on a second device supporting a second quality level different from the first quality level;
• computer code for identifying a media program position maintained at a server for resuming playback;
• computer code for transmitting a second fragment associated with the live media program to the second device, the second fragment including a second fragment number derived using the media program position.
